When you have a smartphone with a built-in speaker or a headset, you may experience some issues because the volume of your media is not controlled by the hardware but by the software. It is therefore not possible to make your smartphone play a video or audio file at the desired level.
The same issue occurs on tablets and other electronic devices that have a built-in speaker or a headset. In these devices, you can only adjust the volume of the device as a whole.
If you experience problems with the audio or media files, the problem is most likely due to the fact that the sound is not coming from the device but from the software.
To solve this problem, you can use Volume Control – Volume Slider. It is an app that allows you to control the volume of your smartphone, tablet, or other electronic devices with a built-in speaker or a headset.
The app is small in size and does not consume much memory.
You can adjust the volume of your media files from the notification panel of your device.
